Basics System Software—NewWorld ROM - 5

New Technologies

System Software—NewWorld ROM

The iBook is the second Macintosh portable to take advantage of ROM-in-RAM architecture. This design features a small ROM that provides hardware initialization functions and provides a mechanism to load the Mac OS ROM image into RAM. The new software architecture that is centered around ROM-in-RAM and its ramifications is named NewWorld.

ROM-in-RAM

Hardware-specific code resides in firmware (ROM) that fits into one ROM called the boot ROM. The boot ROM includes the code and tables needed to start up the computer, load an operating system, and provide common hardware access


services.

All higher-level software resides in what has been historically known as the Mac OS ROM, but with much of the old hardware-specific code moved into the boot ROM. As before, the Mac OS ROM can still be augmented by enablers, the System file, and extensions.

Prior to the iMac, all Macintosh computers required a ROM component that contained many components of the Mac OS software. The NewWorld approach sidesteps this requirement by copying an image of the Mac OS ROM into RAM before the Mac OS begins operation. Once the Mac OS begins operation, a Mac OS ROM image in RAM and an actual Mac OS ROM behave in the same way. No new or different software interfaces are directly accessible from the Mac OS.

During the boot process, software contained in the Mac OS ROM file communicates with Open Firmware to collect


information about the hardware, using the Open Firmware Client Interface.

RAM Footprint

Because the Mac OS ROM image is stored in RAM, approximately 3 MB of RAM is available for other uses. In effect, a system with 64 MB of RAM appears to have only 61 MB available. Some portion of the missing 3 MB is offset by having fewer patches in RAM.

Data Structures and Files

The Mac OS ROM image is contained in a new file, named Mac OS ROM, that resides in the System Folder. The Mac OS ROM image is exactly the same as it would be if it were an actual Mac OS ROM, containing the high-level software, the kernel software, and the 68K emulator.


Startup Disk Control Panel

Previous systems stored the user's selected startup device in Parameter RAM (PRAM) when the user selected a device in the Startup Disk control panel. The startup disk routine for the iBook, rather than setting Mac OS PRAM, sets an Open Firmware config variable called boot-device. Open Firmware honors this setting unless the selected device is unavailable or is overridden by the user.

The following keys can be pressed to override the selected startup device:• Command-Option-Shift-Delete: ignore the boot-device

setting and scan for alternate devices.• C: force the internal CD-ROM drive to be the startup

device.• D: force the internal hard drive to be the startup device.

Drives

Hard Disks and HFS Plus

The iBook hard drives use Mac OS Extended format (HFS Plus). Some disk utility and disk locking programs manufactured by companies other than Apple are incompatible with HFS Plus.

Using an incompatible disk utility or disk locking program could result in hard drive corruption and loss of all data on the hard disk. Check the documentation that came with the program or contact the manufacturer or the vendor of the program before attempting to use it. Apple recommends using the utility Disk First Aid, which is included on the system software CD that ships with the iBook.

Basics Drives - 12

Norton Utilities

±

Warning:

Norton Utilities for Macintosh, v3.5.2 and 3.5.3 will not run on any of the iBook computers. Running versions 3.5.1 and below may cause hard drive corruption and loss of all data on the hard drive. See the Symantec Web site at http://[email protected] for more information on Norton Utilities and Mac OS Extended format.

Basics Memory and Power - 13

Memory and Power

Sleep Memory Extension 1.0

Apple has identified a very rare issue that may occur when putting an iBook to sleep. The computer may be unable to recognize the hard drive at startup. To prevent this from happening, Apple strongly recommends that all iBook customers running systems prior to Mac OS 9.0.4 install the Sleep Memory Extension 1.0.

After installing the Sleep Memory Extension and restarting the iBook, the "Preserve memory contents on sleep" checkbox in the Energy Saver control panel will be dimmed and unavailable.

Download the Sleep Memory Extension 1.0 from the Apple Software Updates Web site at http://www.apple.com/swupdates/.


Battery

The iBook has one lithium-ion (LiIon) battery that will provide up to six hours of battery life when all power saving features are implemented. With the power adapter plugged in, the iBook battery recharges in four hours while the computer is running, or in two hours when the computer is shut down or in sleep mode.

The iBook battery is not compatible with any previous Macintosh portable computer.

No Backup Battery

The iBook has no backup battery. You will lose all data stored in RAM if you change the battery while the system is in sleep mode and no power adapter is connected. Therefore, shut the system down before changing the battery, or make sure a power adapter is connected.


Battery Handling Guidelines

±

Warning:

Lithium-ion (LiIon) batteries contain hazardous chemicals and should not be thrown out with household or office trash. Review battery handling and disposal instructions in Safety Information in Bulletins/Safety.

The following are guidelines for properly handling batteries:• Handle the battery carefully. Do not drop, puncture,

disassemble, mutilate, or incinerate it.• Do not leave a battery in the computer for longer than a

week without plugging in the power adapter.• Do not short the battery contacts.• Do not leave the battery in hot locations (such as the

trunk of a car).• Do not leave a battery in storage for longer than six


months without recharging it.• Never get batteries wet.• Recharge batteries only as described in the user’s manual

and only in ventilated areas.

Battery Verification

When the power adapter is being used, the ring around the power adapter port glows green when the battery is fully charged. The ring glows amber if the battery is being charged.

You can also check the battery status by looking at the Battery portion of the control strip or the battery symbol in the upper right corner of the Finder menu bar.


Power Adapter Verification

Try using a known-good power adapter if the computer cannot run off the existing one, or try the existing power adapter with another iBook or G3 Series PowerBook

Under normal operation, the ring around the power adapter port will glow green or amber if the computer is receiving adequate power. If the computer is not receiving adequate power, the ring will not glow green or amber.

Power Issues

±

Warning:

The iBook has no backup battery. Therefore, shut the system down before changing the battery, or make sure an AC power adapter is connected. Changing the battery while the system is in sleep mode, without a power adapter, will result in a loss of all data stored in RAM.

Sleep

There is an option in the Energy Saver control panel called "Preserve memory contents on sleep." When this option is selected, the system creates a file containing all the information contained in RAM at that time, and stores it on the hard disk before going into sleep mode.


Battery Verification

When the power adapter is being used, the ring around the power adapter port glows green when the battery is fully charged. The ring glows amber if the battery is being charged.

You can also check the battery status by looking at the Battery portion of the control strip or the battery symbol in the upper right corner of the Finder menu bar.

Power Adapter Verification

Try using a known-good power adapter if the computer cannot run off the existing one, or try the existing power adapter with another iBook or G3 Series PowerBook

Under normal operation, the ring around the power adapter port will glow green or amber if the computer is receiving adequate power.

Upgrades Overview - 1

Overview

Customers may wish to upgrade iBook with additional RAM or an AirPort Card. Instructions for performing these upgrades are contained in the user’s manual. A more detailed version is included in this chapter to help you if you are asked to do this for customers.

Important:

Taking the computer apart beyond upgrading RAM or adding an AirPort Card may void the customer’s warranty.

2. Remove the battery cover and pull the battery out of its compartment.


3. Turn the computer over, open it, and place a cloth over the palmrest to protect the surface.

4. If the keyboard is locked, turn the keyboard lock (located to the left of the num lock key) a half turn in either direction until the tab clears the plastic of the top case.


5. Press down on the two keyboard release tabs (located on the keyboard between the F1 and F9 keys), and slide them toward you.

6. When the keyboard pops up, move it away from you to release the tabs in the front.

7. Turn the keyboard over and lay it on top of the palmrest.


8. Pull the bracket handle toward you to free the top edges from the EMI shield.
